Just some silly little thing I thought up. Fairly short, so it won't take up much of your time. Enjoy.

"Bill, stop doing that."

"Doing what, Pinetree?"

"That... thing you're doing."

"What thing?"

"You know exactly what."

"Why?"

"It's making me uncomfortable."

Bill chuckled knowingly. Just to mess with the boy, he changed again, now an even darker shade of yellow.

"Stop it!"

Instead of listening, the demon started lightening back, and Dipper had barely let out a sigh of relief before Bill switched to an alarming shade of green.

"BILL!"

He cackled and floated off, flashing from blue to orange to red to pink, groans of frustration following him.

The next day, Dipper was sitting on the couch reading the journal, when a familiar giggling triangle popped out of nowhere and floated over his shoulder. Dipper sighed and closed the book, turning to ask what the heck he wanted, and almost had a heart attack.

"WHY ARE YOU A CIRCLE!?"

Edit: it has come to my attention that I have insulted some people with my OCD Dipper comment in the summary. I fully apologize, and thank you for pointing it out so nicely. I'll be sure to moderate myself better in the future.
